Works as expected!

TDP limit to 10
gamemoderun %command%

Runs smooth everywhere. Preferentially adjusted FOV to 90. Fans can spin up a bit in the open areas.
works perfectly out of the box, triple digit fps
No issues out of the box.
Runs perfectly out of the box with default Proton
Runs like native
Runs perfectly. Ending sequence eats GPUs for breakfast though.
Works great, looks great. No issues a few hours in.
Just works
If not the described crashing and fullscreen issues I've had, this plays just like a native game, GE proton or upstream.
gamemoderun %command%
Turning off fullscreen in the settings froze the game, forcing me to SIGKILL it. SIGTERM was not enough. Interestingly, this was not always happening, and after re-downloading the game with fullscreen turned off by default, it went away.
Crashed randomly a few times, although this might be a thing with my hardware, I believe.
Using Gnome wayland session with amdgpu, maybe that has any influence on the crashes.
DXVK_FRAME_RATE=75 %command%
40FPS, 5w TDP, 400Mhz GPU, 1152x720 with FSR. Shadow set to 1 and VFX to 0
Changes were made to save some battery, could have lowered resolution/render scale a bit more but didn't care enough. It's a puzzle game with minimalistic graphics so I didn't care about frame rate and graphics
This game works perfectly on Linux and even had a recent update adding some SteamDeck only features which is a gyroscopic photo mode
This game works 100% on Linux with 0 issues so far as the game runs as if it used a native Linux build. Because this game runs so well on Linux, there is no doubt that this runs well on FreeBSD/NetBSD as BSD-systems emulate the Linux Kernel and as such can run Steam.
Enabled gyro to preference, not out of necessity.
Gorgeous on Deck, runs without any issues whatsoever.
Game works without any trouble and I noticed nothing different from expected.

No issues encountered.
Perfect.
Low FPS on 8x antialiasing, otherwise solid performance
works perfectly
Absolutely flawless
Works out of the box
Runs perfectly out of the box; no tweaks, no issues.
Right click on the game, go to "Properties", then under "Compatibility" --> "Force the use of a specific SteamPlay", choose "Proton 5.0-10", because if you use anything later than that, you'll get an error message saying something like "error accessing full screen 1920x1080" or something like that. So, use specifically Proton 5.0-10, and it runs perfectly fine, as if it were native.
8xMSAA dumps my fps from 200 to 30, probably a bug. Works fine otherwise.
No window opens. Eventually stops running.
unable to find any logs. Strangely, I still receive the achievement "orange"
It just works.
I disabled cloud save
After navigating the levels a lot, I managed to make two different levels overlap (as if a ghost one appeared on top of the real one)
Resuming game at second play session, I found my progress and settings were reset. See "customization" line of this report for fix.
